Ahead-of-Time Agent Harness Construction

Ahead-of-Time (AOT) harness construction is an agent optimization paradigm that treats the execution scaffold as a durable, persistent artifact optimized over historical experience before deployment. Under this approach, harness components—such as system prompts, code logic, memory representations, tool registries, and control policies—are tuned across an offline training stream with the objective of generalizing across future tasks, domains, or model versions. While effective when deployment distributions are stable and homogeneous, AOT construction requires the optimization process to precompile a broadly useful runtime scaffold before observing the specific structure of an incoming problem instance.
